SIDNEY HUNTER, OF ST. LOUIS, MISSOURI. PNEumAT-io TIRE.

Specification of Letters Patent.

Patented April a, 1906.

Application filed Eeptember 21,1905. Serial No. 279,485.

act description, reference being had to the accompanying drawings, forming a part hereof; My invention has relation to improvements in pneumatic tires; and it consists in the novel construction of tire more fully set forth in the specification and pointed out in the claim. a I

In the drawin s, Fi ure lis a side elevation of a tire wit I wal s broken away, showing my improvement a plied thereto. Fig. 2 is a cross-section on t e line 2 2 of Fig. 1. Fig. 3 is across-sectional detail of the intermediate reinforcing-section by which the tire is rendered puncture-proof, and Fig. 4 is an enlarged sectional detail showing the coating of enamel or glaze on the outer member of the reinforcing-section.

'The object of my invention is to construct a pneumatic tire which will be practically puncture-proof, one which is and cheap, and" one possessing further and other advantages better apparent from a detailed description of the invention, which is as follows:

Referring to the drawings, W represents a vehicle-wheel of conventional design. The tire made according to my invention is som posed of an inner rubber tube or section lQan outer section or tube 2, and an inner section interposed between the 'arts 1 and 2. This inner section is composed of an outer metallic annular member or sheath 3, encircling the inner section 1 andembracing'the outer half of its peripheral surface, the outer faceof said member. 3 being coated With a layer of enamel or glaze 4, Fig. 4. The glazed surlight, durable,

face, being hard and smooth, notonly resists the puncture by shar p0intssucl1 as nails, spikes, and the like-- ut has the property of eflecting such sharp points, so that the point will sooner slipalong the glazed surface of the layer 4 than it will penetrate it and the metal of the member 3. The opposite edges of the 'members 3 have riveted thereto the elastic extensions 55, made of material similar to the braces ofisuspenders, whereby the extensions can be stretched around the inner section' 1 and then tightly laced thereto by the lacing-strings 6, whihconnect the free edges of,the elastic extensions 5.

A tire of the character here described is practically puncture-proof, since not only does the metal sheath 3 resist the penetrating tendency of sharp pieces of rock, nails, tacks, and the like, but the points will slip over the glazed layer 4 before they will enter the same, We smooth surface of the glaze defleeting such points to ah angle at which penetration becomes irn ossiblc.

Having describe claim is V Apneumatic tire corn rising an inner rubber section, an outer ru intermediate section composed of an outer metal sheath encircling thednner sectionand embracing the outer portion of its peripheral surface, elastic extensions secured to the edges of the sheath, and suitable lacing for uniting the extensions and drawing them tightly about the inne section, substantially as set forth.

In testimony whereof I aflix my signature in presence of two witnesses.
